UNITED STATES PATENT OEEIoE JOHN .FINNEGAN, OF ANN ARBOR, MICHIGAN.

IMPROVEMENE m PLOWS.

Specification forming part of Letters Patent No. 197,623, dated November 27, 1877; application filed September 1, 1877.

To all whom it may concern:

'Be it known that I, JOHN FINNEGAN, of Ann Arbor, in the county of Washtenaw and- State of Michigan, have invented an Improvement in Plows, of which the following is a snecifi- 4 cation:

for adjustably attaching the handles to the standard-plate.

Figure 1 is a side elevation of the plow, looking from land. Fig. 2 is a detached perspective view of the standard-plate. Fig. 3 is a rear elevation of the plow without the angle-block. Fig. 4 is a similar elevation with the angle-block. Fig. 5 is a perspective view of the angle-block.

In the drawings, A represents the point, B the mold-board, (J the land-side, D the beam, and E the handle, of a center-draft plow. F is a cast plate, whose foot F is curved outwardly to receive and support the land-side. The foot is cast with a wing, F which supports the point, and also the toe of the moldboard. The front edge is beveled to support the top of the mold-board, which, with the point and land-side, is secured in position by the usual bolts. An upward extension, F, at the front forms a support for the beam, which is pivoted thereto by a bolt, (1.. A rearward and upward extension, F", supports the tail end of the beam, which is laterally adjustable on an angle-plate, I), cast therewith, and provided with a segment-slot, through which the adjusting-bolt 0 passes. This plate may be cast with a pendent angle, 1), with notches at the sides to receive the handles, which are secured by a transverse tie-bolt, in which case their pitch may be adjusted through a segment-slot, d, in the plate F, through which passes the bolt 0, which secures the front ends of said handles to the sides of said plate. I prefer, however, to omit the pendent angle b, and in lieu thereof to cast a Wing, F on each side of the extension F, with a slot in each, through which the tie-bolt may pass, and to adjust the pitch of the handles at that point.

By referring to Figs. 3 and 4 it will be seen that the body of the plate F is curved toward the mold-board at the top of the land-side, bringing it directly into the center line of draft, as well as clearing it from the land of the furrow in deep plowing;

The drawings, being made from the model, show my improvement attached to a centerdraft plow. I do not desire to confine myself to any particular kind of plow; but

What I claim as my invention, and desire to secure by Letters Patent, is-

The standard-plate F, cast with the angleplate I) and wings F F substantially as and for the purpose set forth.
